Root cause of "no sound, ever": the two audio backend DLLs shipped in the repo are fakes. libsndfile-1.dll exports 15 funcs BY ORDINAL ONLY (no names) and sf_open() always returns NULL; OpenAL32.dll (72KB) imports only KERNEL32 -- no dsound/wasapi/winmm -- so it is a pure no-op that returns fake handles (ctx=0x00000001, alGenSources->0) and never touches the hardware. The whole render->device->buffer->source->play chain ran clean and silent. Fixes: - OpenAL32.dll: replace the stub with the real OpenAL Soft 1.25.2 Win32 build (imports AVRT/ole32/WINMM, real WASAPI backend). The exe imports the 25 AL funcs by NAME so it is a drop-in; alGenSources now yields a live source and alSourcePlay reaches AL_PLAYING. - libsndfile: DROPPED entirely. It is replaced by LoadWavPCM() in L4AUDRES -- a tiny RIFF/WAVE fmt+data reader that loads our soundbank WAVs (16-bit PCM) straight into the AL buffer. Removed the .lib/.dll from the link + copy and git-rm'd the stub. (This also kills the "ordinal 50 could not be located in libsndfile-1.dll" load-failure popup: adding an sf_strerror import bound to an ordinal the 2..16-only stub could not satisfy.) - Soundbank: 241 samples cracked from AUDIO1/2.RES (SF2 v1.0) by tools/sf2extract.py into content/AUDIO/*.wav + the allPresets[2][128] table (audiopresets.cpp), replacing the zero-init btstubs stub. All 241 now load (alErr=0). BT_AUDIO_TEST plays buffer0 as proof-of-life; BT_AUDIO_LOG traces the chain. Remaining: in-game triggering (AudioEntities on fire/step/engine/explosion) so PlayNote fires during play -- next audio wave. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
